A friend of mine and automotive instructor by the name of John Forro once stated that 80% of the emission codes that light the malfunction indicator light (MIL) can be easily diagnosed from the generic or global side of the scan tool, and I would have to agree with him.
If you ask most automotive technicians if they trust an oil life monitor, or OLM, they will typically say “no way” and the reasons for this view will come fast and furiously.
Brake pads without a mechanical retention system have a significantly increased risk of the friction material separating from the backing plate -- which can lead to brake failure.
In today’s world of automotive repair we’re faced with dealing with a broad range of different types of systems in modern day vehicles that reach our service bays.
I’m sure you’ve heard the phrase, “Don’t get pushy.” Well, in the automotive world this phrase seems to have taken on a new meaning. In the last 10 to 15 years or so the number of buttons on a motor vehicle seems to have grown immensely.

It’s all about information. The more we know, the better job we can do. No one is an expert on everything. That’s where information sharing becomes so critical. Every tech has faced a problem wherein the remedy isn’t easily found in a repair manual.

We’re in this together, so let’s help each other out.
Like most shops, mine has become increasingly populated with cordless power equipment, ranging from impact wrenches, drills, saws, grinders, vacuums, a wide array of flashlights, tablets, cell phones, cordless desk phones and on and on.
Turbochargers are essentially compressors that direct more air into the engine’s cylinders in order to produce additional power. A turbo derives its energy source from both temp and pressure of exhaust gas. Intake air enters through the air cleaner into the turbo compressor inlet. The air is compressed which raises air density and volume.
The need to track down electrical system failures in today’s vehicles are more prevalent now than they were many years ago. With the addition of system add-ons such as increased safety items, more entertainment and creature comfort options and overall improved vehicle operating capabilities, the technician is faced with the added complexity of performing proper diagnostics.
The Supplemental Restraint System (SRS); or in GM jargon SIR (supplemental inflatable restraint system) uses more components than just airbags: modules, crash sensors, seat weight and position sensors, seat belt switches, warning lights and pre-tensioning devices are all used to protect and enhance the safety of the driver and passengers.
